A maximum of 30 Form W-2's, Form W-2G's, and Form 1099's are allowed for New Mexico e-file. This return must be filed as a conventional paper return. {NMmandate2}
There's no tax withheld on any of them, right? Combine them into one, or at least combine the ones from the same casino. New Mexico will thank you for saving them the effort of processing a paper return and then storing it.
